My connection isn't like that so much it is more lower noise margin (both upstream and downstream by about 8db). all of the time and attenuation increase after the tie pair mod

do note that this issue is on the upstream path hence noise issues are likely to be close to the exchange
or just in the relevant frequency band regardless of location.

Line is making a clicking noise in 3s (click,click,click, then a pause, then it starts again.

Okay to be fair I should really have updated this a bit more.

The noise is broadband - it affects multiple bins on the upstream path and affects the downstream slightly too, but to a far lesser extent than the upstream.

Affected downstream bins manage 5+ bits / bin. SNR on them is considerably higher than the SNR on the upstream bins affected.

All this implies to me that the noise / issue is likely sourced from near the exchange, which is far from impossible given the placement of the exchange - an industrial estate.

In any case it's academic. This is in the 'can't fix' section for Openreach and will be resolved once FTTC is in place.

Currently struggling with a 120kbps upstream barely holding on. Not great.

you're welcome. It should avoid people thinking upstream problems only occur at the exchange, when you can have household problems limiting the upstream quite badly.

electric fence is the only thing that springs to mind with a low frequency regular pattern. Wind can move overhead lines and do similar things but it would be variable.

You may do betting in the General Broadband Chatter section as this isn't really a notspot issue per se.

It is only intermittent as it can be when the phone is ringing out, it may start to click but then stop, other times there will be no clicking just a hissing noise

Bt have now just reset the snr from 16.0db and have said that there is nothing wrong with the line, but there is clearly as there is a hiss and the attenuation has increased with hundreds of thousands of errors at 6.0db noise margin.
